When treating itching, it is important to first understand the type and symptoms of the itching that are causing the distress.This article will explain the characteristics and symptoms of itchy skin diseases in different parts of the body. Itching that appears all over the body Itching can occur anywhere on the body, not just in specific areas. This article explains the main types of itching that can occur throughout the body. rash/contact dermatitis This refers to inflammation accompanied by itching and redness that occurs when a substance comes into direct contact with the skin.Potential causes of skin irritation include ingredients and surfactants in lotions and hair care products, metal products such as jewelry, and plants and animals such as lacquer. The causes are diverse.Contact dermatitis can be classified into two types: primary irritant contact dermatitis, caused by irritation from a causative substance, and allergic contact dermatitis, caused by an allergic reaction to the causative substance. Urticaria (hives) This condition is characterized by the appearance of intensely itchy red patches or raised wheals on parts of the skin, which then disappear without a trace after a while. While it often subsides within a few hours, some cases can last from half a day to two or three days. Be careful not to scratch, as the intense itching can worsen the symptoms or leave scars.Urticaria that resolves within a month is called acute urticaria, while urticaria that persists longer is called chronic urticaria. Heat rash A sudden increase in sweat secretion from eccrine sweat glands, coupled with thickening of the epidermis around the sweat pores, can block the sweat openings. This causes sweat to accumulate in the sweat glands and ducts, resulting in blister-like heat rash, itching, and inflammatory reactions (such as red rashes). insect bites When you are bitten or stung by insects such as mosquitoes, gnats, fleas, ticks, or bees, an allergic reaction occurs due to substances in the insect, causing itching and inflammation (redness and swelling). Pruritus (skin itching) Pruritus is a condition in which itching occurs despite the absence of any noticeable abnormalities such as redness or eczema on the skin. It is often accompanied by dry skin, and while it can sometimes be caused by systemic or internal organ diseases, itching can also occur in elderly individuals without any specific underlying medical condition. Drug-induced liver injury If liver function is impaired due to side effects of medication, you may experience itchy skin.In addition to itching, other symptoms may include skin symptoms such as redness and rashes, systemic symptoms such as fatigue, fever, and jaundice, and digestive symptoms such as loss of appetite, nausea, and abdominal pain. These symptoms may appear suddenly or persist. Psoriasis The skin is red, and layers of scale-like patches appear on top of it. When scratched, these patches flake off. It is a skin condition that tends to become chronic, and the degree of itching varies depending on the symptoms of psoriasis. Scabies This condition is caused by a type of mite called Sarcoptes scabiei that infests the skin. It results in small blisters or papules, often accompanied by intense itching. Itching that appears on the scalp and face This article explains common types of itching that appear on the scalp and face. dry dermatitis As skin dryness progresses, itchy redness, eczema, and blisters may appear. This condition tends to worsen during the dry seasons from autumn to winter. seborrheic dermatitis This dermatitis is caused by irritation from secreted sebum, and is characterized by redness and rashes on the scalp and face, as well as a flaky, dandruff-like appearance.It tends to appear in areas with high sebum secretion, such as the scalp, face, and armpits. While it often causes itching on the scalp, it doesn't always. Itching that appears on the hands and feet Some types of itching have characteristics that manifest on the hands and feet. This article explains symptoms that commonly appear on the hands and feet. hand eczema This is a general term for eczema symptoms on the hands, and refers to contact dermatitis. Symptoms include redness, small bumps, blisters, and peeling skin on the hands and fingers.This condition occurs when the protective sebum layer of the skin is lost due to frequent hand washing or the use of detergents, and the skin's barrier function is weakened before being irritated. It is often seen in housewives and others who frequently do housework involving water, and is therefore sometimes called housewife's eczema. It is also a common condition among cooks and beauticians who use their hands a lot. Xeroderma/sebum deficiency Due to factors such as aging, the skin's barrier function and sebum secretion decline, leading to a decrease in skin moisture and resulting in dry skin.This condition is seen on the hands, feet, back, and below the knees of elderly people, and is characterized by flaky, peeling, and cracked skin. It is itchy, and scratching can worsen the condition and lead to eczema. It also tends to worsen during the dry seasons from autumn to winter. Athlete's foot / Ringworm Ringworm is caused by a type of fungus called dermatophyte that infects the skin, resulting in itching and blisters. It can infect various parts of the body, but the most common type is tinea pedis, which appears on the feet and is commonly known as athlete's foot.Since ringworm fungi thrive in warm, humid environments, wearing poorly ventilated shoes for extended periods can lead to increased foot moisture and make you more susceptible to infection. Chapped skin During cold winter months, dry skin can develop small cracks on its surface, leading to chapped skin, inflammation, and bleeding. Chapped skin can also be accompanied by itching and pain. chilblains This condition is caused by poor blood circulation due to cold weather, resulting in red rashes and swelling accompanied by itchiness and pain. It is commonly seen in winter and frequently occurs in areas where blood flow to the extremities is poor, such as the hands and feet. Itching in the genital area There are various types of itching that can occur in the delicate area (genitals). Genital candidiasis It is most commonly seen in women and is caused by an abnormal overgrowth of Candida, one of the normal inhabitants of the vagina, resulting in severe itching of the vulva and an increase in white, cheese-like or sake-lees-like vaginal discharge.This condition is more likely to occur when immunity is weakened due to stress or fatigue, but other causes include changes in hormone balance, changes in the balance of resident bacteria due to antibiotics, and high temperature and humidity caused by stuffiness. Trichomonas vaginitis Vaginitis is caused by the parasitic protozoan Trichomonas vaginalis. Symptoms appear after an incubation period of about 10 days, but it is said that about 50% of people do not experience any symptoms. Symptoms include a foul-smelling, droplet-like discharge, severe itching of the vulva, and a tingling or burning sensation.The primary route of infection is through sexual contact, but it can also be transmitted through clothing, towels, bathtubs, etc. Genital warts Infection occurs when the HPV (human papillomavirus) virus comes into contact with small cuts or abrasions on the skin or mucous membranes, resulting in warts around the genitals and anus. While there are usually few noticeable symptoms, some people may experience pain or itching. Anal pruritus Anal pruritus is a condition characterized by itching in and around the anus. The itching tends to worsen when the body warms up, such as after bathing or going to sleep.There are various causes, including hemorrhoids, anal polyps, rectal prolapse, constipation or diarrhea, and psychological factors such as stress. In addition, it can be caused by feces or sweat adhering to the anus or surrounding area, while excessive washing with a bidet or similar device can also weaken the skin's barrier function and cause itching. babies, children This is likely to happenTypes of itching A baby's delicate skin is prone to problems, and the eczema commonly seen in infants is collectively called infant eczema. Let's take a look at the types of infant eczema that cause itching. Infant seborrheic dermatitis Infant eczema, which is seen from the neonatal period to early infancy, is caused by excessive sebum secretion and appears as itchy eczema on the face and scalp. As the condition progresses, scabs may form. heat rash While it is more common in infants and young children, it can also occur in adults. In infants, it often presents as a red rash called miliaria rubra, which can cause itching and pain. Miliaria crystallina, on the other hand, is characterized by small white blisters that appear mainly on the trunk and limbs, and is usually less itchy. Diaper rash Diaper irritation and friction against the skin can cause inflammation, resulting in redness and eczema in the areas covered by the diaper. This can be accompanied by itching and pain, and in severe cases, it can lead to sores and bleeding. Types of itching that are common during pregnancy Various unpleasant symptoms that occur during pregnancy are called minor troubles, and itching is one of them. Pregnancy-related pruritus A characteristic feature of this condition is that while you feel a tingling itch all over your body, there are no visible lesions on the surface of your skin, such as rashes. During pregnancy, hormonal imbalances can cause the skin to become dry, which can also contribute to the itching. Generally, the symptoms subside after childbirth.
